Composition of materials for women&#39;s elastic free size winter shirts

ABSTRACT

A composition of material for manufacturing women&#39;s elastic free size winter shirts having an omasum inner-wall-like textile structure to render desired elasticity to a shirt.  
     The basic composition of material of this invention to render the omasum-like textile structure is composed of wool and polyester.  
     The shirt of this invention is excellent in resilient elasticity, original shape retainability and shape stability. The shirts of this invention is free size, one size fitting all. The shirt is lighter than average women&#39;s winter shirts. Thermal insulation is adequate. Packing size is much smaller than a comparable women&#39;s winter shirts.  
     The shirts of this invention emphasize the bodyline of women&#39;s breast and decorate the line with embossing to render a more sensual appearance.

[0001] The present invention relates to a composition of materials for manufacturing a women's elastic free size winter shirts having excellent resilient elasticity, original shape retainability and shape stability maintaining an omasum inner-wall-like textile structure.

BACKGROUND OF THE INVENTION

[0002] 1. Field of Invention

[0003] The present invention relates to a composition of material for manufacture of a lighter, smaller and more sensual elastic women's free size winter shirts. The omasum-like structure rendered by the procedure of this invention facilitates excellent resilient elasticity, original shape retainability and shape stability to the textile and enables to produce women's shirts which have the elastic and sensual characteristics.

[0004] 2. Description of the Prior Art

[0005] Since they have high performance, synthetic fibers such as nylon and polyester fibers have been widely used for clothing and in industrial areas. Fibrous sheets composed of nylons and polyesters are frequently used as three-dimensional products such as interlining cloths for clothes, brassieres, and pads for breasts and shoulders. Recently, they have been applied to a shape stabilizer of the shirts made of blended yarns containing polyester and cotton.

[0006] Conventional polyester fiber itself is poor in resiliency. To enhance reinsiliency, the fiber should be conjugated with highly resilient animal hair such as horse hair or even human hair for an application to interlining cloths. Sophisticated sewing technique is required to make clothing from the conjugated fibers.

[0007] U.S. Pat. No. 6,248,418 to Taguchi, et al. teaches the methods to manufacture materials having good resiliency, dimensional stability and three dimensional shape retainability from polyester itself by high speed molten polymer taking-up method followed by heat treatments. Taguchi, et al. teach to add materials such as wool to the polyester fiber by variant processing methods.

[0008] Taguchi, et al. teach to make shirts by weaving or knitting yarns made by spinning only staple fiber or yarns made by mix-pinning of the staple fiber and other fibers, sewing it to form a shirt, and heat treating it at a temperature not lower than 120° C. Taguchi, et al. teach an example that a shirt made by the procedure has three dimensional shape retainability and suited to the shape of the body. None is suggested or illustrated about a composition of material for a flexible shirts of free size, retaining the omasum-like structure.

SUMMARY OF THE INVENTION

[0009] It is the object of this invention to provide a new composition of material for manufacture of women's shirts which have an omasum inner wall-like structure to give desired resilient elasticity and original shape retainability enough to make a free size, one size fiting all, shirts.

[0010] The shirt made from the material having composition of this invention is much lighter than average women's winter shirts. Thermal insulation is adequate. Packing size is much smaller than a comparable women's winter wear.

[0011] The materials for these shirts are composed of wool and polyester which are fabricated by hand followed by heating and moisture treatments to make the omasum-like structure.

[0012] The shirts of this invention emphasize the line of women's breast and decorate the bodyline with embossing, which is possible due to the excellent resilient elasticity and original shape retainability rendered to the material by fabricating the material to have the omasum-like structure.

[0013] The weight of a shirt of this invention is less than 200 g/shirt in dry state, which is much lighter than a typical women's knit sweater and winter shirt. They usally weigh over 250 g/shirt.

[0014] The structural characteristics of the shirt of this invention made it possible to manufacture a women's winter shirt of free size which is as warm as other women's winter shirts but the packing volume and weight are smaller than those of typical women's winter shirts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The texture composed of wool and polyester for manufacturing a women's elastic free size winter shirts having an omasum inner-wall-like textile structure was invented.

[0016] When a woman wears the shirt of this invention the degree of stretching of the shirt depends on the the part of women's upper body where the shirt contacts. The textile surrounding breast becomes semi-transparent while the slender waist part remains opaque. Combination of this semi-transparency and opacity along the women's bodyline give a more sensual look.

[0017] When a woman wears the shirt of this invention, the air is captured in the extended unit of omasum-like structure surrounded by the shirts material and wearer's skin and acts as insulating layer rendering adequate thermal insulation to the shirt.

[0018] Wool renders smooth sensual feel to the texture and polyester renders resiliency and drawbility to the texture.

[0019] Best mode of composition of this invention is 25 Wt % wool and 75 Wt % polyester. 

What is claimed is:
 1. A composition of material for manufacture of women's elastic winter shirts having an omasum inner-wall-like textile structure, manufactured as free size, one size fitting all, maintaining their original shape after at least 100 times wearing by a woman of normal size, becoming partly semi-transparent and partly opaque when dressed to set off the upper bodyline of the wearer, the peak density of the omasum-like structure at a normal state is 260 peaks/100 cm², horizontal 20 peaks/10 cm by vertical 13 peaks/10 cm, and the height of one omasum unit being 12 mm, consists of 25 wt % wool and 75 wt % polyester.
 2. The content of wool in claim 1 is in the range of 10 wt % to 30 wt %.
 3. The content of wool in claim 1 is in the range of 1 wt % to 40 wt %
 4. The content of polyester in claim 1 varies from 99 wt % to 70 wt %.
 5. The polyester in claim 1 is a conjugated fiber comprising polyethylene terephthalate and polybutadiene terephthalate.
 6. The polyester in claim 1 is a copolymer of polystyrene based polymer.
 7. The polyester in claim 1 is obtained by adding boric acid or boron compound to polyethylene terephthalate, polybutylene terephthalate and polyester copolymer thereof as the other component.
